Titre de l'invention : Charnière active pour capot de véhicule automobile Title of the invention: Active hinge for motor vehicle hood
[1] jLa présente invention revendique la priorité des demandes françaises 1912055 et 1912066 déposées le 28 Octobre 2019 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. [1] The present invention claims the priority of French applications 1912055 and 1912066 filed on October 28, 2019, the content of which (text, drawings and claims) is incorporated here by reference.
[2] Le contexte technique de la présente invention est celui des équipements de sécurité de véhicules automobiles, et plus particulièrement les équipements conçus pour soulever les capots au niveau de leur partie arrière afin de protéger des piétons en cas d’accidents ou d’autres incidents dus à la circulation. Plus particulièrement, l’invention a trait à une charnière active pour capot de véhicule automobile. [2] The technical context of the present invention is that of the safety equipment of motor vehicles, and more particularly the equipment designed to raise the hoods at the level of their rear part in order to protect pedestrians in the event of accidents or other. traffic incidents. More particularly, the invention relates to an active hinge for a motor vehicle hood.
[3] De manière connue, certains véhicules automobiles comportent un capot « actif » qui est articulé sur une structure du véhicule automobile. Le capot est alors articulé grâce à des moyens de déplacement situés au niveau d’une extrémité arrière du capot, du côté du pare-brise du véhicule automobile. Ces moyens de déplacement vers le haut permettent d’activer le soulèvement de la partie arrière du capot lors d’un effort détecté au niveau d’un parechoc avant du véhicule automobile. L’effort détecté est plus particulièrement un choc piéton. [3] As is known, certain motor vehicles have an "active" hood which is articulated on a structure of the motor vehicle. The hood is then articulated by means of movement located at a rear end of the hood, on the windshield side of the motor vehicle. These upward movement means make it possible to activate the lifting of the rear part of the hood during a force detected at a front bumper of the motor vehicle. The detected force is more particularly a pedestrian impact.
[4] Dans l’état de la technique, on connaît des dispositifs de sécurité pour capot actif de véhicules automobiles munis d’un moyen de déplacement comprenant une charnière de type pantographe. La charnière de type pantographe forme une articulation pour le soulèvement de la partie arrière du capot du véhicule automobile. Cette charnière est en configuration repliée lorsque le capot est verrouillé. Lorsqu’un choc sensiblement frontal est détecté par le dispositif de sécurité, la charnière se déploie grâce à un charnon mobile relié à un charnon fixe par une articulation. [4] In the state of the art, safety devices are known for the active hood of motor vehicles provided with a movement means comprising a pantograph-type hinge. The pantograph-type hinge forms an articulation for lifting the rear part of the hood of the motor vehicle. This hinge is in the folded configuration when the cover is locked. When a substantially frontal impact is detected by the safety device, the hinge deploys thanks to a movable knuckle connected to a fixed knuckle by a hinge.
[5] L’inconvénient de ces dispositifs de sécurité munis d’une charnière de type pantographe est qu’ils sont lourds et volumineux et ainsi peu adaptés aux contraintes économiques actuelles du secteur automobile.
[6] On connaît par ailleurs des dispositifs de sécurité pour capots actifs de véhicules automobiles munis d’un charnon mobile, d’un charnon fixe et d’une béquille. Lorsqu’un choc sensiblement frontal est détecté par le dispositif de sécurité, le charnon mobile se déplace par rapport au charnon fixe, fixé solidairement à la structure dudit véhicule automobile, ce qui permet de soulever la partie arrière du capot. L’ouverture du charnon mobile produit un effet levier sur la béquille, qui est configurée pour soutenir le capot en position haute. La béquille est guidée dans son mouvement à la fois par une coopération entre l’une de ses extrémités et le charnon mobile, et également par une coopération entre une autre de ses extrémités et le charnon fixe. [5] The drawback of these safety devices provided with a pantograph-type hinge is that they are heavy and bulky and thus poorly suited to the current economic constraints of the automotive sector. [6] Safety devices are also known for active hoods of motor vehicles provided with a movable knuckle, a fixed knuckle and a crutch. When a substantially frontal impact is detected by the safety device, the movable knuckle moves relative to the fixed knuckle, fixed integrally to the structure of said motor vehicle, which makes it possible to lift the rear part of the bonnet. Opening the movable knuckle leverages the kickstand, which is configured to support the hood in the up position. The crutch is guided in its movement both by cooperation between one of its ends and the mobile knuckle, and also by cooperation between another of its ends and the fixed knuckle.
[7] Les documents JPH1199906 et JPH34925 décrivent différents types de charnières actives comportant un charnon fixe et un charnon mobile. [7] The documents JPH1199906 and JPH34925 describe different types of active hinges comprising a fixed knuckle and a movable knuckle.
[8] La présente invention a pour objet de proposer une nouvelle charnière active pour capot de véhicule automobile offrant une alternative aux dispositifs de sécurité pour capots actifs connus, et de conduire en outre à d’autres avantages. [8] The object of the present invention is to provide a novel active hinge for a motor vehicle hood offering an alternative to the known active hood safety devices, and further to lead to other advantages.
[9] Un autre but de l’invention est de proposer une charnière active pour capot de véhicule automobile qui soit fiable dans son fonctionnement. [9] Another object of the invention is to provide an active hinge for a motor vehicle hood which is reliable in its operation.
[10] Un autre but de l’invention est de proposer une charnière active pour capot de véhicule automobile qui soit simple, tant du point de vue de sa mise en œuvre, que du point de vue de sa fabrication. [10] Another object of the invention is to provide an active hinge for a motor vehicle hood which is simple, both from the point of view of its implementation and from the point of view of its manufacture.
[11] Un autre but de l’invention est de proposer une charnière active pour capot de véhicule automobile qui soit peu onéreuse, de sorte à ne pas impacter négativement le coût du véhicule automobile qui se veut économique. [11] Another object of the invention is to provide an active hinge for a motor vehicle hood which is inexpensive, so as not to negatively impact the cost of the motor vehicle, which is intended to be economical.
[12] Un autre but de l’invention est de proposer une charnière active pour capot de véhicule automobile qui soit universelle et polyvalente. [12] Another object of the invention is to provide an active motor vehicle hood hinge which is universal and versatile.
[13] Selon un premier aspect de l’invention, on atteint au moins l’un des objectifs précités avec une charnière active pour capot de véhicule automobile comportant un charnon fixe destiné à être fixé solidairement à une structure du véhicule automobile et par rapport à laquelle le capot est destiné à être soulevé, un charnon mobile destiné à être fixé solidairement au capot afin de pouvoir en contrôler son ouverture, et une béquille couplée en rotation avec ledit charnon mobile par un organe de couplage en rotation, la béquille comprenant en outre un organe de
retenu, remarquable en ce que le charnon fixe comprend une zone de blocage destinée à collaborer avec l’organe de retenue de la béquille afin de maintenir ladite charnière active dans une configuration déployée ; et une zone de guidage destinée à collaborer avec l’organe de retenue afin de l’orienter vers la zone de blocage lors de l’ouverture de la charnière active. [13] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with an active hinge for a motor vehicle hood comprising a fixed knuckle intended to be fixedly attached to a structure of the motor vehicle and with respect to which the cover is intended to be raised, a movable knuckle intended to be fixedly attached to the cover in order to be able to control its opening, and a crutch coupled in rotation with said movable knuckle by a rotating coupling member, the crutch further comprising an organ of retained, remarkable in that the fixed knuckle comprises a locking zone intended to collaborate with the retaining member of the crutch in order to maintain said active hinge in a deployed configuration; and a guide zone intended to collaborate with the retaining member in order to orient it towards the blocking zone during the opening of the active hinge.
[14] Le charnon mobile de la charnière active conforme au premier aspect de l’invention est mobile par rapport au charnon fixe qui est destiné à être fixe à la structure du véhicule automobile. Le charnon mobile est mobile lorsque la charnière s’ouvre ou se ferme. [14] The movable knuckle of the active hinge according to the first aspect of the invention is movable relative to the fixed knuckle which is intended to be fixed to the structure of the motor vehicle. The movable knuckle is movable when the hinge opens or closes.
[15] Ainsi, le charnon fixe collabore avec une béquille de la charnière active, au niveau de l’organe de retenue de ladite béquille, lors de l’ouverture de la charnière active et à l’issue de l’ouverture de la charnière active. [15] Thus, the fixed knuckle works with a crutch of the active hinge, at the level of the retaining member of said crutch, during the opening of the active hinge and at the end of the opening of the hinge active.
[16] La zone de blocage du charnon fixe et la zone de guidage du charnon fixe sont des zones du charnon fixe destinées à loger l’organe de retenue de la béquille. [16] The fixed knuckle blocking zone and the fixed knuckle guide zone are areas of the fixed knuckle intended to house the crutch retainer.
[17] La zone de blocage du charnon fixe est configurée pour bloquer la béquille. Notamment, la zone de blocage du charnon fixe est configurée pour bloquer la béquille en une position de soutien du capot et la charnière active en configuration déployée. La zone de blocage du charnon prend la forme d’un logement pour l’organe de retenue de la béquille. [17] The fixed knuckle blocking zone is configured to block the kickstand. In particular, the blocking zone of the fixed knuckle is configured to block the prop in a support position for the cover and the active hinge in the deployed configuration. The locking area of the knuckle takes the form of a housing for the crutch retainer.
[18] La zone de blocage du charnon fixe est configurée pour bloquer l’organe de retenue de la béquille, en ce sens que l’organe de retenue ne peut en être délogé que par une force extérieure au charnon fixe et/ou à la béquille. En l’absence de cette force extérieure, l’organe de retenue de la béquille, une fois logé dans la zone de blocage, y est maintenu. En collaborant avec l’organe de retenue de la béquille, la zone de blocage du charnon fixe participe au maintien de la béquille en position de soutien du capot. [18] The blocking zone of the fixed knuckle is configured to block the crutch retaining member, in that the retaining member can only be dislodged from it by a force external to the fixed knuckle and / or the crutch. crutch. In the absence of this external force, the crutch retainer, once housed in the blocking area, is held there. By working with the stand retainer, the fixed knuckle blocking zone helps to keep the stand in the bonnet support position.
[19] La zone de blocage du charnon fixe est configurée pour collaborer par engagement avec l’organe de retenue de la béquille. Par exemple, la zone de blocage a une forme au moins en partie complémentaire avec une forme de l’organe de retenue de la béquille.
[20] La zone de guidage du charnon fixe conforme au premier aspect de l’invention est configurée pour guider l’organe de retenue de la béquille vers la zone de blocage du charnon fixe. En collaborant avec l’organe de retenue de la béquille, la zone de guidage du charnon fixe participe au positionnement de la béquille en une position de soutien du capot. [19] The blocking zone of the fixed knuckle is configured to collaborate by engagement with the crutch retaining member. For example, the blocking zone has a shape at least partly complementary to a shape of the crutch retaining member. [20] The guide zone of the fixed knuckle according to the first aspect of the invention is configured to guide the support member of the crutch towards the blocking zone of the fixed knuckle. By working with the support member of the crutch, the guide zone of the fixed knuckle participates in the positioning of the crutch in a support position for the cover.
[21] Le charnon fixe conforme au premier aspect de l’invention est configuré pour que l’organe de retenue passe successivement, et dans cet ordre, de la zone de guidage du charnon fixe à la zone de blocage du charnon fixe. La zone de guidage du charnon fixe et la zone de blocage du charnon fixe sont des zones adjacentes dans le charnon fixe. La zone de guidage du charnon fixe est configurée pour guider l’organe de retenue de la béquille dans un déplacement de translation. Ainsi, la zone de guidage du charnon fixe est configurée pour loger de façon transitoire l’organe de retenue de la béquille. En ce sens, la zone de guidage du charnon fixe est configurée pour autoriser une mobilité de l’organe de retenue de la béquille. [21] The fixed knuckle according to the first aspect of the invention is configured so that the retainer passes successively, and in that order, from the guide zone of the fixed knuckle to the locking zone of the fixed knuckle. The guide zone of the fixed knuckle and the blocking zone of the fixed knuckle are adjacent zones in the fixed knuckle. The guide zone of the fixed knuckle is configured to guide the crutch retainer in a translational movement. Thus, the guide zone of the fixed knuckle is configured to temporarily house the crutch retaining member. In this sense, the guide zone of the fixed knuckle is configured to allow mobility of the crutch retainer.
[22] La zone de blocage du charnon fixe est configurée pour bloquer la béquille de sorte à l’immobiliser en translation suite à l’entrainement de la béquille par le charnon mobile de la charnière active. La zone de blocage du charnon fixe est configurée pour autoriser une mise en rotation de l’organe de retenue de la béquille. La zone de blocage du charnon fixe est configurée pour autoriser un déplacement de l’organe de retenue de la béquille suite à la force extérieure telle que précédemment décrite. [22] The blocking zone of the fixed knuckle is configured to block the crutch so as to immobilize it in translation following the drive of the crutch by the movable knuckle of the active hinge. The fixed knuckle blocking zone is configured to allow rotation of the crutch retainer. The fixed knuckle blocking zone is configured to allow movement of the crutch retainer following the external force as previously described.
[23] La zone de guidage du charnon fixe est configurée pour collaborer par engagement avec l’organe de retenue de la béquille. Par exemple, la zone de guidage du charnon fixe est configurée pour crocheter l’organe de retenue de la béquille. [23] The fixed knuckle guide zone is configured to collaborate by engagement with the crutch retainer. For example, the guide zone of the fixed knuckle is configured to hook the crutch retainer.
[24] L’invention conforme à son premier aspect permet ainsi avantageusement de guider la béquille de la charnière active vers sa position de soutien du capot, puis de maintenir la béquille de la charnière active dans cette position de soutien du capot.
[25] Le charnon fixe de charnière active comprend avantageusement au moins un des perfectionnements ci-dessous, les caractéristiques techniques formant ces perfectionnements pouvant être prises seules ou en combinaison : [24] The invention in accordance with its first aspect thus advantageously makes it possible to guide the prop of the active hinge towards its support position of the bonnet, then to maintain the prop of the active hinge in this support position of the bonnet. [25] The fixed active hinge knuckle advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements can be taken alone or in combination:
[26] - la zone de guidage est délimitée par un bord inférieur et un bord supérieur libre situé à distance du bord inférieur, le bord inférieur et le bord supérieur formant ensemble un canal de guidage de l’organe de retenue vers la zone de blocage. Le bord inférieur de la zone de guidage et le bord supérieur du canal de guidage délimitent le canal de guidage. Le canal de guidage forme un passage configuré pour guider l’organe de retenue vers la zone de blocage lors de son déplacement en translation. En d’autres termes, le bord inférieur de la zone de guidage et le bord supérieur du canal de guidage sont configurés pour autoriser le déplacement de l’organe de retenue dans le canal de guidage. Par exemple, le bord inférieur de la zone de guidage et le bord supérieur du canal de guidage présentent une surface continue et/ou lisse le long de laquelle l’organe de retenue peut glisser ; [26] - the guide zone is delimited by a lower edge and a free upper edge located at a distance from the lower edge, the lower edge and the upper edge together forming a guide channel from the retaining member to the blocking zone . The lower edge of the guide zone and the upper edge of the guide channel delimit the guide channel. The guide channel forms a passage configured to guide the retainer towards the blocking zone during its translational movement. In other words, the lower edge of the guide area and the upper edge of the guide channel are configured to allow movement of the retainer in the guide channel. For example, the lower edge of the guide zone and the upper edge of the guide channel have a continuous and / or smooth surface along which the retainer can slide;
[27] - le bord inférieur de la zone de guidage comprend une première partie rectiligne. Par rectiligne, on entend que la première partie du bord inférieur de la zone de guidage s’étend en une ligne sensiblement droite, incitant ainsi l’organe de guidage à suivre un mouvement de translation au niveau de ladite première partie du bord inférieur de la zone de guidage ; [27] - the lower edge of the guide zone comprises a first rectilinear part. By rectilinear is meant that the first part of the lower edge of the guide zone extends in a substantially straight line, thus prompting the guide member to follow a translational movement at said first part of the lower edge of the guide. guide zone;
[28] - le bord inférieur de la zone de guidage comprend une deuxième partie située dans une configuration intermédiaire entre la première partie et la zone de blocage, la deuxième partie formant un coude par rapport à la première partie dudit bord inférieur. Par « formant un coude », on entend que la deuxième partie du bord inférieur de la zone de guidage forme un angle saillant dans le bord inférieur. Lorsque l’organe de retenue de la béquille se déplace en translation le long de la deuxième partie du bord inférieur de la zone de guidage, il est amené à changer brusquement de direction. En changeant brusquement de direction, l’organe de retenue de la béquille est orienté vers la zone de blocage ; [28] - the lower edge of the guide zone comprises a second part situated in an intermediate configuration between the first part and the blocking zone, the second part forming an elbow with respect to the first part of said lower edge. By “forming an elbow” is meant that the second part of the lower edge of the guide zone forms a projecting angle in the lower edge. When the crutch retainer moves in translation along the second part of the lower edge of the guide zone, it is caused to change direction abruptly. By abruptly changing direction, the crutch retainer is oriented towards the blocking area;
[29] - le bord inférieur de la zone de guidage comprend (i) une première partie rectiligne, et (ii) une deuxième partie située dans une configuration intermédiaire entre la première partie et la zone de blocage, la deuxième partie formant un
coude par rapport à la première partie dudit bord inférieur. Lorsque l’organe de retenue de la béquille se déplace en translation le long du bord inférieur de la zone de guidage, il emprunte une direction rectiligne le long de la première partie du bord inférieur de la zone de guidage, puis change de direction en suivant la direction donnée par la deuxième partie du bord inférieur de la zone de guidage, de sorte à entrer dans la zone de blocage du charnon fixe ; [29] - the lower edge of the guide zone comprises (i) a first rectilinear part, and (ii) a second part located in an intermediate configuration between the first part and the blocking zone, the second part forming a elbow relative to the first part of said lower edge. When the stand retainer moves in translation along the lower edge of the guide zone, it takes a rectilinear direction along the first part of the lower edge of the guide zone, then changes direction following the direction given by the second part of the lower edge of the guide zone, so as to enter the blocking zone of the fixed knuckle;
[30] - le bord supérieur du canal de guidage comprend une partie terminale libre rectiligne. Par rectiligne, on entend que la partie terminale libre du bord supérieur du canal de guidage s’étend en ligne sensiblement droite. Par sensiblement droite on entend que la partie terminale libre du bord supérieur du canal de guidage a une surface qui incite l’organe de guidage à conserver une même trajectoire lors de son déplacement en translation au niveau de ladite partie terminale libre du bord supérieur du canal de guidage. Dans le charnon fixe, la partie terminale libre du bord supérieur du canal de guidage est opposée à la zone de blocage du charnon fixe. En ce sens, la partie terminale libre du bord supérieur du canal de guidage participe à délimiter une entrée du canal de guidage ; [30] - the upper edge of the guide channel comprises a free rectilinear end part. By rectilinear is meant that the free end part of the upper edge of the guide channel extends in a substantially straight line. By substantially straight is meant that the free end part of the upper edge of the guide channel has a surface which encourages the guide member to keep the same path during its translational movement at said free end part of the upper edge of the channel. guidance. In the fixed knuckle, the free end part of the upper edge of the guide channel is opposite the blocking zone of the fixed knuckle. In this sense, the free end part of the upper edge of the guide channel participates in delimiting an entrance to the guide channel;
[31] - le bord supérieur du canal de guidage comprend une partie proximale à la zone de blocage et formant un coude par rapport à la partie terminale libre dudit bord supérieur. Par « formant un coude », on entend que la partie proximale du bord supérieur du canal de guidage forme un angle saillant dans le bord supérieur. Lorsque l’organe de retenue de la béquille se déplace en translation le long de la partie proximale du bord supérieur du canal de guidage, il est amené à changer brusquement de direction. En changeant brusquement de direction, l’organe de retenue de la béquille est orienté vers la zone de blocage ; [31] - the upper edge of the guide channel comprises a part proximal to the blocking zone and forming an elbow with respect to the free end part of said upper edge. By “forming an elbow” is meant that the proximal part of the upper edge of the guide channel forms a projecting angle in the upper edge. As the crutch retainer moves in translation along the proximal portion of the upper edge of the guide channel, it is caused to abruptly change direction. By abruptly changing direction, the crutch retainer is oriented towards the blocking area;
[32] - le bord supérieur du canal de guidage comprend (i) une partie terminale libre rectiligne, et (ii) une partie proximale à la zone de blocage et formant un coude par rapport à la partie terminale libre dudit bord supérieur. Lorsque l’organe de retenue de la béquille se déplace en translation le long du bord supérieur du canal de guidage, il emprunte une direction rectiligne le long de la partie terminale du bord supérieur du canal de guidage, puis change de direction en suivant la direction donnée par la partie proximale du bord supérieur du canal de guidage, de sorte à entrer dans la zone de blocage du charnon fixe ;
[33] - le canal de guidage comprend une zone d’amorçage délimitée par la partie terminale libre du bord supérieur et par la première partie du bord inférieure, la partie terminale libre du bord supérieur et la première partie du bord inférieure formant ensemble un angle non nul. En d’autres termes, la partie terminale libre du bord supérieur et la première partie du bord inférieure ne sont pas parallèles entre elles.

L’organe de retenue de la béquille est configuré pour bloquer la béquille dans la position de soutien du capot avec le charnon fixe. Conformément à l’invention, la charnière active est maintenue en configuration déployée grâce à la béquille, bloquée par la coopération entre l’organe de retenue et la zone de blocage du charnon fixe. Dans le véhicule automobile qu’elle équipe, la charnière active est configurée pour passer de la configuration pliée à la configuration déployée suite à un choc piéton sensiblement frontal audit véhicule automobile. [45] The prop of the active hinge according to the first aspect of the invention is intended to support the hood of the motor vehicle following the deployment of the active hinge. The kickstand retainer is configured to lock the kickstand in the hood support position with the fixed knuckle. According to the invention, the active hinge is maintained in the deployed configuration by means of the crutch, blocked by the cooperation between the retaining member and the blocking zone of the fixed knuckle. In the motor vehicle that it equips, the active hinge is configured to switch from the folded configuration to the deployed configuration following a pedestrian impact substantially frontal to said motor vehicle.
[46] Dans un mode de réalisation de l’invention, la béquille comprend une partie supérieure comprenant l’organe de couplage en rotation avec le charnon mobile, une partie inférieure comprenant l’organe de retenue avec le charnon fixe, une partie intermédiaire située entre la partie supérieure et la partie inférieure ; la partie intermédiaire est configurée pour, d’une part, être rigide et indéformable au regard d’un effort nominal correspondant au moins à une masse du capot avec lequel la
béquille est destinée à collaborer et, d’autre part, pour être déformable au regard d’un effort - dit d’accident - prédéfini et supérieur à l’effort nominal. [46] In one embodiment of the invention, the crutch comprises an upper part comprising the coupling member in rotation with the movable knuckle, a lower part comprising the retaining member with the fixed knuckle, an intermediate part located between the upper part and the lower part; the intermediate part is configured to, on the one hand, be rigid and undeformable with regard to a nominal force corresponding at least to a mass of the cover with which the crutch is intended to collaborate and, on the other hand, to be deformable with regard to a force - called accident - predefined and greater than the nominal force.
[47] Ainsi, la béquille est destinée à collaborer avec la charnière active et avec le capot du véhicule automobile associé à la charnière active. Selon l’invention, dans le véhicule automobile qu’elle équipe, la béquille permet (i) d’arrêter la levée du capot lorsqu’une hauteur suffisante est atteinte, et (ii) de soutenir le capot du véhicule automobile lorsque la charnière active avec laquelle la béquille est destinée à collaborer est déployée. La béquille permet également de relâcher le capot du véhicule automobile lorsque l’effort exercé sur la béquille dépasse une valeur seuil, typiquement lorsqu’un choc apparaît sur le capot maintenu par la béquille. [47] Thus, the crutch is intended to collaborate with the active hinge and with the hood of the motor vehicle associated with the active hinge. According to the invention, in the motor vehicle that it equips, the stand makes it possible (i) to stop the lifting of the hood when a sufficient height is reached, and (ii) to support the hood of the motor vehicle when the hinge activates with which the crutch is intended to collaborate is deployed. The stand also makes it possible to release the hood of the motor vehicle when the force exerted on the stand exceeds a threshold value, typically when an impact appears on the hood held by the stand.
[48] En d’autres termes, la béquille est destinée à soutenir le capot du véhicule automobile qu’elle équipe jusqu’à ce que l’effort d’accident soit appliqué audit capot, tel que par exemple lorsque le piéton percute le véhicule automobile au niveau du capot du véhicule automobile. Alors, conformément à l’invention, sous l’effort d’accident, la béquille se déforme élastiquement ou plastiquement pour pouvoir faire redescendre le capot du véhicule automobile qu’elle équipe, de sorte à amortir ledit effort d’accident. [48] In other words, the stand is intended to support the hood of the motor vehicle that it equips until the accident force is applied to said hood, such as for example when the pedestrian hits the vehicle. automobile at the hood of the motor vehicle. Then, in accordance with the invention, under the stress of an accident, the stand deforms elastically or plastically in order to be able to lower the hood of the motor vehicle it is equipped with, so as to cushion said accident stress.
[49] L’organe de retenue comprend par exemple un axe qui s’étend perpendiculairement à la béquille. Lorsque la béquille est formée par une plaque, le plan d’élongation de la béquille est perpendiculaire ou sensiblement perpendiculaire à la plaque. L’organe de retenue est en saillie de la plaque, ce qui le configure pour pouvoir coopérer avec le charnon fixe de la charnière active ; [49] The retainer comprises, for example, an axis which extends perpendicular to the crutch. When the crutch is formed by a plate, the elongation plane of the crutch is perpendicular or substantially perpendicular to the plate. The retainer protrudes from the plate, which configures it to be able to cooperate with the fixed knuckle of the active hinge;
[50] La partie supérieure de la béquille comprend une ouverture circulaire destinée à collaborer avec un axe de rotation solidaire du charnon mobile de la charnière active. L’organe de couplage en rotation de la partie supérieure de la béquille comprend l’ouverture circulaire de la partie supérieure de la béquille. Avantageusement, l’ouverture circulaire de la partie supérieure de la béquille est configurée pour coopérer par engagement d’une forme complémentaire du charnon mobile de la charnière active. L’ouverture circulaire participe à la mise en œuvre de la béquille selon le premier aspect de l’invention. Lors du déploiement de la charnière active à laquelle la béquille est associée, l’ouverture
circulaire de la partie supérieure de la béquille participe à faire passer la béquille de la position de repos à la position de soutient du capot du véhicule automobile. [50] The upper part of the crutch comprises a circular opening intended to collaborate with an axis of rotation integral with the movable knuckle of the active hinge. The upper crutch rotational coupling member includes the circular opening of the upper crutch. Advantageously, the circular opening of the upper part of the crutch is configured to cooperate by engaging a complementary shape of the movable knuckle of the active hinge. The circular opening participates in the implementation of the crutch according to the first aspect of the invention. When deploying the active hinge to which the crutch is associated, the opening circular of the upper part of the stand helps to move the stand from the rest position to the position of supporting the hood of the motor vehicle.
[51] La charnière active conforme au premier aspect de l’invention comprend aussi avantageusement au moins un des perfectionnements ci-dessous, les caractéristiques techniques formant ces perfectionnements pouvant être prises seules ou en combinaison : [51] The active hinge according to the first aspect of the invention also advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements can be taken alone or in combination:

[54] - l’ouverture de guidage est délimitée par deux bords longitudinaux qui s’étendent en direction de l’organe de couplage en rotation, un angle non nul séparant les deux bords longitudinaux. En d’autres termes, les deux bords longitudinaux ne sont pas parallèles entre eux. Les deux bords longitudinaux sont destinés à coopérer avec l’ergot de guidage du charnon mobile de la charnière active. Les bords longitudinaux de l’ouverture de guidage de la partie supérieure de la béquille guident ladite béquille lorsqu’elle passe de la position de repos à la position de soutien du capot ; [54] - the guide opening is delimited by two longitudinal edges which extend in the direction of the coupling member in rotation, a non-zero angle separating the two longitudinal edges. In other words, the two longitudinal edges are not parallel to each other. The two longitudinal edges are intended to cooperate with the guide lug of the movable knuckle of the active hinge. The longitudinal edges of the guide opening in the upper part of the crutch guide said crutch as it passes from the rest position to the support position of the bonnet;
[55] - l’ouverture de guidage comprend, au niveau d’un bord inférieur situé du côté de la zone intermédiaire de la béquille, une zone de blocage de l’ergot de
guidage du charnon mobile de la charnière active. La zone de blocage de l’ouverture de guidage de la partie supérieure de la béquille conforme au premier aspect de l’invention est configurée pour bloquer la béquille en position de soutien du capot du véhicule automobile équipé de ladite béquille. Au niveau de sa zone de blocage, l’ouverture de guidage de la partie supérieure de la béquille est destinée à bloquer le déploiement du charnon mobile de la charnière active, via son ergot de guidage ; [55] - the guide opening comprises, at the level of a lower edge located on the side of the intermediate zone of the crutch, a blocking zone of the lug of guiding of the movable knuckle of the active hinge. The blocking zone of the guide opening of the upper part of the crutch in accordance with the first aspect of the invention is configured to block the crutch in the supporting position of the hood of the motor vehicle equipped with said crutch. At its blocking zone, the guide opening of the upper part of the crutch is intended to block the deployment of the movable knuckle of the active hinge, via its guide lug;
[56] - la zone de blocage de l’ouverture de guidage prend la forme d’un arc de cercle formé au niveau d’une extrémité inférieure de l’un des bords longitudinaux. L’arc de cercle a un diamètre égal ou sensiblement égal à celui de l’ergot de guidage du charnon mobile de la charnière active avec laquelle la béquille est destinée à collaborer. L’arc de cercle a un rayon de courbure orienté vers la partie supérieure de la béquille ; [56] - the blocking zone of the guide opening takes the form of an arc of a circle formed at a lower end of one of the longitudinal edges. The arc of a circle has a diameter equal to or substantially equal to that of the guide lug of the movable knuckle of the active hinge with which the crutch is intended to collaborate. The arc of a circle has a radius of curvature oriented towards the upper part of the crutch;
[57] - la partie supérieure de la béquille forme un angle non nul avec la partie intermédiaire de ladite béquille. En particulier, l’angle formé entre la partie supérieure et la partie intermédiaire de la béquille est compris entre 10° et 45°. L’angle formé entre la partie supérieure et la partie intermédiaire de la béquille est avantageusement égal à 30°. L’angle formé entre la partie supérieure et la partie intermédiaire de la béquille est mesuré sur la béquille n’ayant pas subi de déformation et/ou n’ayant pas subi d’effort d’accident. Autrement dit, l’angle formé entre la partie supérieure et la partie intermédiaire de la béquille est mesuré sur une béquille ayant une partie intermédiaire intègre. Par exemple, l’angle formé entre la partie supérieure et la partie intermédiaire de la béquille est mesuré en position de repos ou en position de soutien ; [57] - the upper part of the crutch forms a non-zero angle with the intermediate part of said crutch. In particular, the angle formed between the upper part and the intermediate part of the crutch is between 10 ° and 45 °. The angle formed between the upper part and the intermediate part of the crutch is advantageously equal to 30 °. The angle formed between the upper part and the intermediate part of the crutch is measured on the crutch which has not undergone any deformation and / or which has not undergone an accident stress. In other words, the angle formed between the upper part and the middle part of the crutch is measured on a crutch having an integrated middle part. For example, the angle formed between the upper part and the middle part of the crutch is measured in the rest position or in the support position;
[58] - l’organe de retenue de la partie inférieure de la béquille s’étend sensiblement perpendiculairement à un plan d’élongation de la béquille. Lorsque la béquille est formée par une plaque, le plan d’élongation de la béquille est perpendiculaire ou sensiblement perpendiculaire à la plaque. L’organe de retenue est en saillie de la plaque, ce qui le configure pour pouvoir coopérer avec le charnon fixe de la charnière active ; [58] - the lower part of the crutch retainer extends substantially perpendicular to a crutch elongation plane. When the crutch is formed by a plate, the elongation plane of the crutch is perpendicular or substantially perpendicular to the plate. The retainer protrudes from the plate, which configures it to be able to cooperate with the fixed knuckle of the active hinge;
[59] - selon un premier exemple de réalisation, l’organe de retenue est issu de matière avec la béquille. On entend par « issus de matière » le fait que, dans le
béquille conforme au premier aspect de l’invention, l’organe de retenue ne peut être séparé de la béquille sans qu’il ne soit porté atteinte à tout ou partie de leur intégrité. Ainsi, selon l’invention, l’organe de retenue et la béquille forment un ensemble qualifié de monobloc du fait qu’ils ne forment ensemble qu’une seule et même pièce continue, faite d’un seul tenant et obtenue au cours d’un même procédé de fabrication. Une telle béquille est par ailleurs plus rigide et plus légère. Selon un deuxième exemple de réalisation alternatif au premier exemple de réalisation, l’organe de retenue est rapporté sur la béquille et fixé solidairement à ladite béquille par des moyens de fixations détachables ou permanents. Un exemple de moyen de fixation détachable est par vissage. Un exemple de moyen de fixation permanent est un moyen de fixation non détachable, tel que par exemple par brasage ; [59] - according to a first embodiment, the retaining member is made from material with the crutch. The term “derived from matter” is understood to mean the fact that, in the crutch according to the first aspect of the invention, the retaining member cannot be separated from the crutch without affecting all or part of their integrity. Thus, according to the invention, the retaining member and the crutch form a unit qualified as a single piece owing to the fact that they form together a single continuous part, made in one piece and obtained during the same manufacturing process. Such a crutch is also more rigid and lighter. According to a second alternative embodiment to the first embodiment, the retaining member is attached to the crutch and integrally fixed to said crutch by detachable or permanent fixing means. An example of a detachable fastening means is by screwing. An example of a permanent fixing means is a non-detachable fixing means, such as for example by soldering;
[60] - l’organe de retenue comprend un axe qui s’étend perpendiculairement à la béquille. L’axe formant l’organe de retenue prend par exemple la forme d’un rivet solidarisé au niveau de l’une de ses extrémités à la béquille ; [60] - the retainer comprises an axis which extends perpendicular to the crutch. The axis forming the retaining member takes for example the form of a rivet secured at one of its ends to the crutch;
[61] - la partie intermédiaire de la béquille comprend au moins une zone d’amincissement local de matière. La zone d’amincissement local permet de concentrer les contraintes mécaniques qui apparaissent dans la béquille, notamment, les contraintes dues à l’effort d’accident. Autrement dit, la zone d’amincissement local permet de concentrer les contraintes mécaniques qui apparaissent lorsque le choc que l’on souhaite amortir intervient ; [61] - the intermediate part of the stand includes at least one area of local thinning of material. The local thinning zone makes it possible to concentrate the mechanical stresses which appear in the crutch, in particular, the stresses due to the accident force. In other words, the local thinning zone makes it possible to concentrate the mechanical stresses that appear when the shock that one wishes to dampen occurs;
[62] - la partie intermédiaire de la béquille comprend deux zones d’amincissement local directement adjacentes et qui sont séparées par une zone de plus grande largeur de la partie intermédiaire de la béquille. La zone de plus grande largeur de la partie intermédiaire de la béquille est, dans la partie intermédiaire, plus large que les zones d’amincissement local. Une zone d’amincissement local présente une largeur inférieure ou sensiblement égale à une épaisseur de la béquille. A contrario, la zone de plus grande largeur de la partie intermédiaire de la béquille séparant deux zones d’amincissement local adjacentes présente une largeur au moins trois fois supérieure à la largeur de la zone d’amincissement local. La zone de plus grande largeur de la partie intermédiaire de la béquille permet de renforcer la partie intermédiaire de sorte à ce que la béquille assure sa fonction de soutien dans la position de soutien du capot du véhicule automobile
qu’elle équipe. Plus particulièrement, la partie intermédiaire de la béquille comprend trois zones d’amincissement local et deux zones de plus grande largeur de la partie intermédiaire de la béquille. Les zones d’amincissement local de la partie intermédiaire de la béquille sont alors séparées deux à deux par l’une des deux zones de plus grande largeur de la partie intermédiaire de la béquille ; [62] - the intermediate part of the crutch comprises two directly adjacent local thinning zones which are separated by a zone of greater width from the intermediate part of the crutch. The area of greatest width of the intermediate part of the crutch is, in the intermediate part, wider than the local thinning areas. A local thinning zone has a width less than or substantially equal to a thickness of the crutch. Conversely, the area of greatest width of the intermediate part of the crutch separating two adjacent local thinning areas has a width at least three times greater than the width of the local thinning area. The area of greater width of the intermediate part of the crutch makes it possible to reinforce the intermediate part so that the crutch performs its supporting function in the supporting position of the hood of the motor vehicle which team. More particularly, the intermediate part of the crutch comprises three zones of local thinning and two zones of greater width of the intermediate part of the crutch. The local thinning zones of the intermediate part of the crutch are then separated in pairs by one of the two zones of greater width of the intermediate part of the crutch;
[63] - chaque zone d’amincissement local de la partie intermédiaire de la béquille est délimitée de part et d’autre par un profil circulaire ou elliptique ; [63] - each local thinning zone of the intermediate part of the crutch is delimited on both sides by a circular or elliptical profile;
[64] - la béquille comprend, au niveau de sa partie inférieure, une dérive qui s’étend simultanément perpendiculairement à la partie inférieure de la béquille et à l’organe de retenue de ladite béquille. La dérive de la partie inférieure de la béquille est destinée à corriger le positionnement relatif de la béquille par rapport au charnon fixe de la charnière active. La dérive prend la forme d’une portée prismatique formée au niveau de la partie inférieure de la béquille. Avantageusement, l’organe de retenue est situé entre la dérive et une extrémité terminale inférieure de la béquille ; [64] - the crutch comprises, at its lower part, a fin which extends simultaneously perpendicular to the lower part of the crutch and to the retaining member of said crutch. The drift of the lower part of the crutch is intended to correct the relative positioning of the crutch with respect to the fixed knuckle of the active hinge. The fin takes the form of a prismatic scope formed at the bottom of the crutch. Advantageously, the retaining member is located between the fin and a lower terminal end of the crutch;
[65] - la dérive forme un angle sensiblement perpendiculaire avec la partie intermédiaire de la béquille. Avantageusement, par rapport à la partie intermédiaire de la béquille, la dérive s’étend à l’opposé de l’organe de couplage en rotation de la partie supérieure de la béquille ; [65] - the fin forms a substantially perpendicular angle with the intermediate part of the crutch. Advantageously, with respect to the intermediate part of the crutch, the fin extends away from the rotational coupling member of the upper part of the crutch;
[66] - la béquille prend la forme d’une plaque. La béquille est alors une pièce globalement plane, qui s’étend dans un plan principal. Une telle béquille est peu encombrante et a une fabrication simplifiée ; [66] - the crutch takes the form of a plate. The crutch is then a generally flat part, which extends in a main plane. Such a crutch is compact and has a simplified manufacture;
[67] - une épaisseur de la plaque est comprise entre 2 mm et 5 mm.

[82] Selon un deuxième aspect de l’invention, il est proposé un véhicule automobile comprenant une structure et un capot monté mobile en rotation par rapport à la structure par l’intermédiaire d’une charnière active conforme au premier aspect de l’invention. Suite à un choc piéton sensiblement frontal, le piéton est généralement projeté, avant de retomber sur le véhicule automobile qu’il a percuté et de subir un nouveau choc correspondant à l’effort d’accident. C’est un choc ayant lieu au niveau du capot du véhicule automobile. Le véhicule automobile conforme au deuxième aspect de l’invention est configuré pour limiter la gravité du choc sensiblement frontal entre le piéton et ledit véhicule automobile. [82] According to a second aspect of the invention, there is proposed a motor vehicle comprising a structure and a cover mounted movable in rotation relative to the structure by means of an active hinge in accordance with the first aspect of the invention. . Following a substantially frontal pedestrian impact, the pedestrian is generally thrown, before falling back on the motor vehicle that he has struck and undergoing a new impact corresponding to the accident stress.

L’entrée de l’organe de retenue 42 de la béquille 2 de la charnière active 13 dans la zone de guidage 70 du charnon fixe 14 initie la sous-étape d’amorçage, comprise dans l’étape de guidage. [154] During the initial step, the crutch 2 is in the rest position and the retaining member 42 of the crutch 2 is free, at a distance from the inlet 78 of the guide channel 77, separate from the fixed knuckle 14 It is only when the crutch 2 of the active hinge 13 is rotated by the movable knuckle 16 of the active hinge 13 that the retaining member 42 of the crutch 2 of the active hinge 13 crosses the entrance 78 of the active hinge 13. guide channel 77 of the fixed knuckle 14. The entry of the retaining member 42 of the stand 2 of the active hinge 13 in the guide zone 70 of the fixed knuckle 14 initiates the priming sub-step, included in the 'guiding step.
[155] Lors de la sous-étape d’amorçage, qui a lieu pendant l’ouverture de la charnière active 13, la zone de guidage 70 du charnon fixe 14 collabore avec l’organe de retenue 42 de la béquille 2 de la charnière active 13 afin de l’orienter
vers la zone de blocage 71 du charnon fixe 14. Comme la zone d’amorçage 83 du canal de guidage 77 va en se rétrécissant vers la zone de couplage 84 du canal de guidage 77, la zone d’amorçage 83 du canal de guidage 77 assure un guidage en translation de l’organe de retenue 42 de la béquille 2 de la charnière active 13 contre le bord supérieur 75 de la zone de guidage 70 du charnon fixe 14 et/ou le bord inférieur 76 de la zone de guidage 70. [155] During the priming sub-step, which takes place during the opening of the active hinge 13, the guide zone 70 of the fixed knuckle 14 collaborates with the retaining member 42 of the crutch 2 of the hinge active 13 in order to orient it towards the blocking zone 71 of the fixed knuckle 14. As the priming zone 83 of the guide channel 77 tapers towards the coupling zone 84 of the guide channel 77, the priming zone 83 of the guide channel 77 guiding in translation the retaining member 42 of the stand 2 of the active hinge 13 against the upper edge 75 of the guide zone 70 of the fixed knuckle 14 and / or the lower edge 76 of the guide zone 70.
[156] Lors d’une sous-étape de couplage inclue dans l’étape de guidage, le canal de guidage 77 coudé permet que l’organe de retenue 42 de la béquille 2 suive le mouvement de rotation. Le mouvement de rotation est imposé par le charnon mobile 16 de la charnière active 13 entraînant la béquille 2 de la charnière active 13. La sous-étape d’amorçage se termine lorsque l’organe de retenue 42 de la béquille 2 de la charnière active 13 entre dans la zone de couplage 84 du charnon fixe 14. Lorsque l’organe de retenue 42 de la béquille 2 de la charnière active 13 est dans la zone de couplage 84 du charnon fixe 14, c’est la sous-étape de couplage, ici non illustrée. La sous-étape de couplage se termine lorsque l’organe de retenue 42 de la béquille 2 de la charnière active 13 entre dans la zone de blocage 71 du charnon fixe 14. [156] During a coupling substep included in the guiding step, the angled guide channel 77 allows the retainer 42 of the crutch 2 to follow the rotational movement. The rotational movement is imposed by the movable knuckle 16 of the active hinge 13 driving the stand 2 of the active hinge 13. The priming sub-step ends when the retaining member 42 of the stand 2 of the active hinge 13 enters the coupling zone 84 of the fixed knuckle 14. When the retaining member 42 of the crutch 2 of the active hinge 13 is in the coupling zone 84 of the fixed knuckle 14, this is the coupling substep , here not shown. The coupling sub-step ends when the retaining member 42 of the crutch 2 of the active hinge 13 enters the locking zone 71 of the fixed knuckle 14.

Autrement dit, la partie intermédiaire 26 de la béquille 2 est plus étroite que la partie supérieure 24 de la béquille 2. [183] A distance measured perpendicular to the elongation axis 28 of the intermediate part 26 of the crutch 2 between the side edges 45 of the intermediate part 26 of the crutch 2 is shorter than a distance between the first peripheral edge 29 of the upper part 24 of the crutch 2 and of the second peripheral edge 30 of the upper part 24 of the crutch 2 and measured perpendicular to the axis of extension 27 of the upper part 24 of the crutch 2. In other words, the intermediate part 26 of the crutch 2 is narrower than the upper part 24 of the crutch 2.
[184] La partie intermédiaire 26 de la béquille 2 comprend au moins une zone d’amincissement local 23 de matière. Une zone d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 est délimitée de part et d’autre par un
profil circulaire de sorte à former deux échancrures 46 dans les bords latéraux 45 de la partie intermédiaire 26 de la béquille 2. [184] The intermediate part 26 of the crutch 2 comprises at least one local thinning zone 23 of material. A local thinning zone 23 of the intermediate part 26 of the crutch 2 is delimited on either side by a circular profile so as to form two notches 46 in the side edges 45 of the intermediate part 26 of the crutch 2.
[185] En l’espèce, la partie intermédiaire 26 de la béquille 2 comprend trois zones d’amincissement local 23, les zones d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 étant directement adjacentes deux à deux. Deux zones d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 directement adjacentes sont séparées par une zone de plus grande largeur 47 de la partie intermédiaire 26 de la béquille 2. En l’espèce, la partie intermédiaire 26 de la béquille 2 comprend deux zones de plus grande largeur 47 identiques.[185] In this case, the intermediate part 26 of the crutch 2 comprises three local thinning zones 23, the local thinning zones 23 of the intermediate part 26 of the crutch 2 being directly adjacent in pairs. Two local thinning zones 23 of the intermediate part 26 of the directly adjacent crutch 2 are separated by a zone of greater width 47 of the intermediate part 26 of the crutch 2. In this case, the intermediate part 26 of the crutch 2 comprises two zones of greater width 47 identical.
L’une des zones d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 relie une des zones de plus grande largeur 47 de la partie intermédiaire 26 de la béquille 2 à la partie inférieure 25 de la béquille 2, et l’autre des zones d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 relie l’autre des zones de plus grande largeur 47 de la partie intermédiaire 26 de la béquille 2 à la partie supérieure 24 de la béquille 2. One of the local thinning zones 23 of the intermediate part 26 of the crutch 2 connects one of the areas of greater width 47 of the intermediate part 26 of the crutch 2 to the lower part 25 of the crutch 2, and the another of the local thinning zones 23 of the intermediate part 26 of the crutch 2 connects the other of the zones of greater width 47 of the intermediate part 26 of the crutch 2 to the upper part 24 of the crutch 2.
[186] La zone d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 est aussi une zone où l’épaisseur mesurée entre la première face 20 de la plaque 19 et la deuxième face 21 de la plaque 19 est plus petite par rapport à l’épaisseur 22 mesurée au niveau de la partie supérieure 24 de la béquille 2 et au niveau de la partie inférieure 25 de la béquille 2 et au niveau de la zone de plus grande largeur 47 de la partie intermédiaire 26 de la béquille 2. [186] The local thinning zone 23 of the intermediate part 26 of the crutch 2 is also a zone where the thickness measured between the first face 20 of the plate 19 and the second face 21 of the plate 19 is smaller by in relation to the thickness 22 measured at the level of the upper part 24 of the crutch 2 and at the level of the lower part 25 of the crutch 2 and at the level of the area of greatest width 47 of the intermediate part 26 of the crutch 2 .
[187] Les FIGURES 9 à 14 illustrent de façon schématique des étapes successives mettant en œuvre la béquille 2 lors d’un choc piéton sensiblement frontal au véhicule automobile 1. Ces étapes successives sont comprises dans un procédé d’amortissement d’un effort d’accident et illustrent la coopération entre la béquille 2, le charnon fixe 14 de la charnière active 13 conforme au premier aspect de l’invention et le charnon mobile 16 de la charnière active 13. [187] FIGURES 9 to 14 schematically illustrate successive steps implementing the stand 2 during a pedestrian impact substantially frontal to the motor vehicle 1. These successive steps are included in a method of damping a force d 'accident and illustrate the cooperation between the crutch 2, the fixed knuckle 14 of the active hinge 13 according to the first aspect of the invention and the movable knuckle 16 of the active hinge 13.
[188] La FIGURE 9 montre une situation préalable au choc sensiblement frontal. La FIGURE 9 illustre la charnière active 13 lorsqu’elle est fermée, c’est à dire repliée sur elle-même. La béquille 2 est en position de repos. Le capot 3 du véhicule automobile 1 est en position basse.
[189] La béquille 2 coopère avec le charnon mobile 16 de la charnière active 13. L’ouverture circulaire 36 de l’organe de couplage en rotation 34 de la partie supérieure 24 de la béquille 2 est associée à l’axe de rotation 17 du charnon mobile 16 de la charnière active 13. L’ergot de guidage 39 du charnon mobile 16 de la charnière active 13 est engagé dans l’ouverture de guidage 35 de l’organe de couplage en rotation 34 de la partie supérieure 24 de la béquille 2. [188] FIGURE 9 shows a situation prior to the substantially frontal impact. FIGURE 9 illustrates the active hinge 13 when it is closed, that is to say folded back on itself. The stand 2 is in the rest position. The hood 3 of the motor vehicle 1 is in the low position. [189] The crutch 2 cooperates with the movable knuckle 16 of the active hinge 13. The circular opening 36 of the rotational coupling member 34 of the upper part 24 of the crutch 2 is associated with the axis of rotation 17 of the movable knuckle 16 of the active hinge 13. The guide pin 39 of the movable knuckle 16 of the active hinge 13 is engaged in the guide opening 35 of the rotational coupling member 34 of the upper part 24 of the kickstand 2.
[190] La béquille 2 est dissociée du charnon fixe 14 de la charnière active 13. L’organe de retenue 42 de la partie inférieure 25 de la béquille 2, qui s’étend perpendiculairement à la plaque de la béquille 2, est libre. [190] The crutch 2 is separate from the fixed knuckle 14 of the active hinge 13. The retaining member 42 of the lower part 25 of the crutch 2, which extends perpendicularly to the plate of the crutch 2, is free.
[191 ] Le charnon mobile 16 de la charnière active 13 est fixée par un rivet de blocage 48. Le rivet de blocage 48 bloque la rotation du charnon mobile 16 de la charnière active 13 selon l’axe de rotation 17, de sorte à ce que ledit charnon mobile 16 soit maintenu fermé. En l’espèce, le rivet de blocage 48 est un point de soudure entre deux éléments mobiles du charnon mobile 16 de la charnière active 13, plus particulièrement entre un élément de liaison terminal 16a et un élément de liaison intermédiaire 16b du charnon mobile 16. L’élément de liaison terminal 16a est fixé au capot 3, et l’élément intermédiaire 16b relie l’élément de liaison terminal 16a au charnon fixe 14. L’élément de liaison terminal 16a et l’élément de liaison intermédiaire 16b sont articulés entre eux au niveau de la ligne de rotation 18, qui forme par exemple un axe de rotation. [191] The movable knuckle 16 of the active hinge 13 is fixed by a locking rivet 48. The locking rivet 48 blocks the rotation of the movable knuckle 16 of the active hinge 13 along the axis of rotation 17, so that that said movable knuckle 16 is kept closed. In this case, the locking rivet 48 is a weld point between two movable elements of the movable knuckle 16 of the active hinge 13, more particularly between a terminal connecting element 16a and an intermediate connecting element 16b of the movable knuckle 16. The terminal connection element 16a is fixed to the cover 3, and the intermediate element 16b connects the terminal connection element 16a to the fixed knuckle 14. The terminal connection element 16a and the intermediate connection element 16b are articulated between them at the level of the rotation line 18, which for example forms an axis of rotation.
[192] L’organe de détection 9 de choc sensiblement frontal du véhicule automobile 1 est raccordé électriquement à un actionneur 49. L’actionneur 49 est configuré pour piloter une ouverture de la charnière active 13 en libérant le charnon mobile 16 de la charnière active 13 du rivet de blocage 48. [192] The substantially frontal impact detection device 9 of the motor vehicle 1 is electrically connected to an actuator 49. The actuator 49 is configured to control an opening of the active hinge 13 by releasing the movable knuckle 16 from the active hinge 13 of the locking rivet 48.
[193] La FIGURE 10 montre une situation de choc sensiblement frontal. La FIGURE 10 illustre la charnière active 13 lorsqu’elle est fermée, c’est à dire lorsque le charnon mobile 16 de la charnière active 13 est replié sur lui-même. La béquille 2 est en position de repos. Le capot 3 du véhicule automobile 1 est en position basse. [193] FIGURE 10 shows a substantially frontal impact situation. FIGURE 10 illustrates the active hinge 13 when it is closed, that is to say when the movable knuckle 16 of the active hinge 13 is folded back on itself. The stand 2 is in the rest position. The hood 3 of the motor vehicle 1 is in the low position.
[194] L’organe de détection 9 du véhicule automobile 1 détecte le choc sensiblement frontal, représenté par une flèche pleine 50. L’organe de détection
9 du véhicule automobile 1 active l’actionneur 49, qui initie la rupture du rivet de blocage 48 comme représenté par un éclair 51. C’est l’étape d’actionnement. [194] The detection unit 9 of the motor vehicle 1 detects the substantially frontal impact, represented by a solid arrow 50. The detection unit 9 of the motor vehicle 1 activates the actuator 49, which initiates the breaking of the locking rivet 48 as represented by a flash 51. This is the actuation step.
[195] La FIGURE 11 montre une situation immédiatement consécutive au choc sensiblement frontal correspondant à une étape d’ouverture de la charnière active 13. La FIGURE 11 illustre la charnière active 13 lorsqu’elle est en train de s’ouvrir comme représenté par la double flèche 51 , c’est à dire lorsque le charnon mobile 16 de la charnière active 13 se déploie. Par effet levier, la béquille 2 se soulève. Le capot 3 du véhicule automobile 1 est poussé de la position basse à la position haute. [195] FIGURE 11 shows a situation immediately following the substantially frontal impact corresponding to a step of opening the active hinge 13. FIGURE 11 illustrates the active hinge 13 when it is in the process of opening as represented by FIG. double arrow 51, that is to say when the movable knuckle 16 of the active hinge 13 is deployed. By lever effect, the stand 2 is raised. The hood 3 of the motor vehicle 1 is pushed from the low position to the high position.
[196] Le rivet de blocage 48 rompu lors de l’étape d’actionnement permet l’ouverture de la charnière active 13 lors d’étape d’ouverture de la charnière active 13. L’étape d’ouverture de la charnière active 13 comprend une étape d’engagement, une étape de rotation du charnon mobile 16 de la charnière active 13, et une étape de guidage. [196] The locking rivet 48 broken during the actuation step allows the opening of the active hinge 13 during the step of opening the active hinge 13. The step of opening the active hinge 13 comprises an engagement step, a step of rotating the movable knuckle 16 of the active hinge 13, and a guiding step.
[197] Lors de l’étape de rotation du charnon mobile 16 de la charnière active 13, le charnon mobile 16 de la charnière active 13 se déploie par un mouvement de rotation autour de la ligne de rotation 18. Le charnon mobile 16 de la charnière active 13, fixé solidairement au capot 3 du véhicule automobile 1, le soulève comme montré par un arc fléché 54. La charnière active 13 entraîne en rotation la béquille 2 selon l’axe de rotation 17 du charnon mobile 16 de la charnière active 13, de sorte à positionner la béquille 2 en position de soutien du capot 3 du véhicule automobile 1. [197] During the step of rotating the movable knuckle 16 of the active hinge 13, the movable knuckle 16 of the active hinge 13 is deployed by a rotational movement around the line of rotation 18. The movable knuckle 16 of the active hinge 13, fixed integrally to the hood 3 of the motor vehicle 1, raises it as shown by an arrowed arc 54. The active hinge 13 rotates the stand 2 along the axis of rotation 17 of the movable hinge 16 of the active hinge 13 , so as to position the stand 2 in the support position of the hood 3 of the motor vehicle 1.
[198] Lors de l’étape d’engagement, la béquille 2 en rotation autour de l’axe de rotation 17 du charnon mobile 16 de la charnière active 13 s’engage avec le charnon fixe 14 de la charnière active 13. En l’espèce, un crochet 52 du charnon fixe 14 de la charnière active 13 guide s’engage avec l’organe de retenue 42 de la partie inférieure 25 de la béquille 2. La coopération entre la béquille 2 et la charnière active 13 qui a lieu niveau de la partie inférieure 25 de la béquille 2, avec l’organe de retenue 42 de la partie inférieure 25 de la béquille 2 et le crochet 52, permet de bloquer la béquille 2 en position de soutien du capot 3 du véhicule automobile 1 lorsque l’organe de retenue 42 de la partie inférieure 25 de la béquille 2 arrive en buttée d’un fond 53 du crochet 52.
[199] Lors de l’étape de guidage, l’ergot de guidage 39 du charnon mobile 16 de la charnière active 13 est guidé dans l’ouverture de guidage 35 de l’organe de couplage en rotation 34 de la partie supérieure 24 de la béquille 2. La rotation de la béquille 2 autour de l’axe de rotation 17 du charnon mobile 16 de la charnière active 13 est accompagnée par l’ergot de guidage 39 du charnon mobile 16 de la charnière active 13 qui est maintenu entre les bords longitudinaux 38 de l’ouverture de guidage 35 de l’organe de couplage en rotation 34 de la partie supérieure 24 de la béquille 2, jusqu’à ce que ledit ergot de guidage 39 se loge au niveau de la zone de blocage 60 de l’ouverture de guidage 35 de l’organe de couplage en rotation 34 de la partie supérieure 24 de la béquille 2. [198] During the engagement step, the stand 2 rotating around the axis of rotation 17 of the movable knuckle 16 of the active hinge 13 engages with the fixed knuckle 14 of the active hinge 13. At l In this case, a hook 52 of the fixed knuckle 14 of the active hinge 13 guide engages with the retaining member 42 of the lower part 25 of the crutch 2. The cooperation between the crutch 2 and the active hinge 13 which takes place level of the lower part 25 of the leg 2, with the retaining member 42 of the lower part 25 of the leg 2 and the hook 52, makes it possible to lock the leg 2 in the supporting position of the hood 3 of the motor vehicle 1 when the retaining member 42 of the lower part 25 of the crutch 2 comes into abutment with a bottom 53 of the hook 52. [199] During the guiding step, the guide pin 39 of the movable knuckle 16 of the active hinge 13 is guided in the guide opening 35 of the rotational coupling member 34 of the upper part 24 of the crutch 2. The rotation of the crutch 2 around the axis of rotation 17 of the movable knuckle 16 of the active hinge 13 is accompanied by the guide pin 39 of the movable knuckle 16 of the active hinge 13 which is held between the longitudinal edges 38 of the guide opening 35 of the rotational coupling member 34 of the upper part 24 of the crutch 2, until said guide lug 39 is lodged at the level of the locking zone 60 of the guide opening 35 of the rotational coupling member 34 of the upper part 24 of the crutch 2.
[200] La FIGURE 12, la FIGURE 13 et la FIGURE 14 montrent que la partie intermédiaire 26 de la béquille 2 est configurée pour, d’une part, être rigide et indéformable au regard d’un effort nominal correspondant au moins à la masse du capot 3 du véhicule automobile 1 avec lequel la béquille 2 collabore et, d’autre part, pour être déformable - élastiquement ou plastiquement - au regard de l’effort d’accident. [200] FIGURE 12, FIGURE 13 and FIGURE 14 show that the intermediate part 26 of the stand 2 is configured to, on the one hand, be rigid and undeformable with regard to a nominal force corresponding at least to the mass of the hood 3 of the motor vehicle 1 with which the stand 2 works and, on the other hand, to be deformable - elastically or plastically - with regard to the accident force.
[201] La FIGURE 12 montre une situation intermédiaire, consécutive au choc sensiblement frontal et précédent un choc sur le capot 3 du véhicule automobile[201] FIGURE 12 shows an intermediate situation, following the substantially frontal impact and preceding an impact on the hood 3 of the motor vehicle
1. En effet, suite à un choc piéton sensiblement frontal, le piéton est généralement projeté, avant de retomber sur le véhicule automobile 1 qu’il a percuté et de subir un choc au niveau du capot 3 du véhicule automobile 1 , générant l’effort d’accident. La FIGURE 12 correspond à une étape de maintien en position ouverte de la charnière active 13. La FIGURE 12 illustre la charnière active 13 lorsqu’elle est ouverte, en position déployée. La béquille 2 est en position de soutien du capot 3 du véhicule automobile 1. Le capot 3 du véhicule automobile 1 est en position haute et maintenu en position haute par la béquille1. Indeed, following a pedestrian impact substantially frontal, the pedestrian is generally thrown, before falling back on the motor vehicle 1 that he has struck and undergo an impact at the hood 3 of the motor vehicle 1, generating the accident effort. FIGURE 12 corresponds to a step of maintaining the active hinge 13 in the open position. FIGURE 12 illustrates the active hinge 13 when it is open, in the deployed position. The stand 2 is in the support position of the hood 3 of the motor vehicle 1. The hood 3 of the motor vehicle 1 is in the high position and held in the high position by the stand.
2. La masse du capot 3 du véhicule automobile 1 génère un effort nominal 55 sur la charnière active 13, et notamment sur la béquille 2. La béquille 2 permet de soutenir la masse du capot 3 du véhicule automobile 1 puisque les zones d’amincissement local 23 de la partie intermédiaire 26 de la béquille 2 sont rigides et indéformables au regard de l’effort nominal 55. 2. The mass of the hood 3 of the motor vehicle 1 generates a nominal force 55 on the active hinge 13, and in particular on the stand 2. The stand 2 makes it possible to support the mass of the hood 3 of the motor vehicle 1 since the thinning zones room 23 of the intermediate part 26 of the stand 2 are rigid and undeformable with regard to the nominal force 55.
[202] La FIGURE 13 correspond à une étape de survenue d’un effort d’accident 56. La FIGURE 13 montre une situation de choc sur le capot 3 du véhicule
automobile 1 générant l’effort d’accident 56. La FIGURE 13 illustre la charnière active 13 lorsqu’elle est ouverte, en position déployée. La béquille 2 est en position de soutien du capot 3 du véhicule automobile 1 mais à un point de rupture du fait de l’effort d’accident 56, puisqu’elle est déformable au regard de l’effort d’accident 56 comme représenté par un autre éclair 57. Le capot 3 du véhicule automobile 1 est en position haute. [202] FIGURE 13 corresponds to a stage of occurrence of an accident force 56. FIGURE 13 shows a situation of impact on the hood 3 of the vehicle. automobile 1 generating the accident force 56. FIGURE 13 illustrates the active hinge 13 when it is open, in the deployed position. The stand 2 is in the support position of the hood 3 of the motor vehicle 1 but at a breaking point due to the accident force 56, since it is deformable with regard to the accident force 56 as represented by another flash 57. The hood 3 of the motor vehicle 1 is in the high position.
[203] La FIGURE 14 montre une situation consécutive au choc sur le capot 3 du véhicule automobile 1 ayant généré l’effort d’accident 56. Il s’agit d’une étape de fermeture de la charnière active 13. La FIGURE 14 illustre la charnière active 13 lorsque le charnon mobile 16 de la charnière active 13 se referme, comme illustré par une flèche pleine descendante 58, en une position affaissée. La béquille 2 est dans une position de relaxe. La béquille 2 est rompue et sa fonction de soutien du capot 3 du véhicule automobile 1 lui fait alors défaut, de sorte à ce que ledit capot 3 du véhicule automobile 1 s’affaisse dans une position intermédiaire comme montré par une flèche arquée 59. Le capot 3 du véhicule automobile 1 accompagne ainsi le choc au niveau du capot 3 du véhicule automobile 1. [203] FIGURE 14 shows a situation following the impact on the bonnet 3 of the motor vehicle 1 having generated the accident force 56. This is a step of closing the active hinge 13. FIGURE 14 illustrates the active hinge 13 when the movable knuckle 16 of the active hinge 13 closes, as illustrated by a solid downward arrow 58, in a collapsed position. The crutch 2 is in a relaxed position. The stand 2 is broken and its function of supporting the hood 3 of the motor vehicle 1 then fails, so that said hood 3 of the motor vehicle 1 sags in an intermediate position as shown by an arched arrow 59. The hood 3 of the motor vehicle 1 thus accompanies the impact on the hood 3 of the motor vehicle 1.
[204] En synthèse, l’invention concerne une béquille 2 pour charnière active 13 de capot 3 de véhicule automobile 1. La béquille 2 est configurée pour coopérer avec une charnière active 13 qui rend mobile en rotation ladite béquille 2 par un effet levier. La béquille 2 comprend une partie supérieure 24 fixée solidairement à une partie inférieure 25 par l’intermédiaire d’une partie intermédiaire 26. La partie supérieure 24 de la béquille 2 comprend un organe de couplage en rotation 34 configuré pour entrer en rotation avec un charnon mobile 16 de la charnière active 13. La partie inférieure 25 de la béquille 2 comprend un organe de retenue 42 configuré pour retenir la béquille 2 lorsqu’elle coopère avec un charnon fixe 14 de la charnière active 13. La partie intermédiaire 26 de la béquille 2 est configurée pour être de faible résistance lorsque soumise à un effort d’accident 56, supérieur à un effort nominal 55 et prédéterminé, de sorte à perdre son intégrité sous l’effort d’accident 56. Ainsi, si la partie intermédiaire 26 de la béquille 2 reste rigide et indéformable en deçà de l’effort d’accident 56, et notamment lorsqu’elle doit supporter une masse du capot 3 du véhicule
automobile 1 correspondant à l’effort nominal 55, est déformable lorsque soumise à l’effort d’accident 56. [204] In summary, the invention relates to a crutch 2 for an active hinge 13 of the hood 3 of a motor vehicle 1. The crutch 2 is configured to cooperate with an active hinge 13 which makes said crutch 2 movable in rotation by a lever effect. The crutch 2 comprises an upper part 24 fixed integrally to a lower part 25 by means of an intermediate part 26. The upper part 24 of the crutch 2 comprises a rotational coupling member 34 configured to enter into rotation with a knuckle. movable 16 of the active hinge 13. The lower part 25 of the crutch 2 comprises a retaining member 42 configured to retain the crutch 2 when it cooperates with a fixed knuckle 14 of the active hinge 13. The intermediate part 26 of the crutch 2 is configured to be of low resistance when subjected to an accident force 56, greater than a nominal force 55 and predetermined, so as to lose its integrity under the accident force 56. Thus, if the intermediate part 26 of the stand 2 remains rigid and undeformable below the accident force 56, and in particular when it has to support a mass of the hood 3 of the vehicle automobile 1 corresponding to the nominal force 55, is deformable when subjected to the accident force 56.
